OF NEW YORK, N. Y., ASSIGNOR TO NATHAN & DREYFUS, OF SAME PLACE.

APPARATUS FOR OILlNG AND LUBRICATING THE BEARINGS AND CYLINDERS 0F STEAM-ENGINES.

SPECIFICATION forming part of Letters Patent No. 237,716, dated February 15, 1881.

Application filed January 3, 188] To all whom it may concern:

Be it known that I, JOHN ABSTERDAM, of the city, county, and State-of New York, have invented certain new and useful Improve ments in Apparatus for Oiling or Lubricating the Cylinders and Bearings of Steam-Engines, and for other Purposes, of which the following is a specification.

My improvement relates to that kind of lubricator in which the feed of' the oil is disclosed by the upward passage of the oil-drops through the body of water contaiuedin a glass or other transparent case.

The accompanying drawing represents, in vertical central section, a lubricating oil-feeding apparatus containing my improvements.

A is the oil-chamber, and B the oil-outlet pipe, which leads from the upper partof the chamber down through the bottom of the same into the tubular shank or plug 0. The oil in the chamber is raised so as to-gradually pass over into the pipe B by the hydrostatic action of a column of water which enters the lower part of the oil-chamber through the pipe 1), and operates substantially in the manner described in my Letters Patent No. 11,598 of November 21, 1854.

Into the base of the plug 0 screws one end of the large U-shaped pipe 15. The other end of this pipe is connected by a screw-threaded coupling-sleeve, F, with a glass tube, G, which virtually forms a continuation of said pipe. The upper end of this glass tube enters a socket in the tubular hub or boss H, projecting laterally from the wall of the oil-chamber, and at its lower end rests in a seat formed in the screw threaded bearing and couplingsleeve F, into .which it is pressed by a screwthreaded tubular and laterally-perforated plug,

(No model.)

J, which screws into H. The tube communicates through the lateral perforations d in plug J with the interior of the hub or boss H,

into which latter is screwed the pipe I which conducts the oil to the parts to be lubricated.

(Joncentrically within the U'-shaped pipe Eis placed the similarly-bent smaller pipe I), which is screwed at one end into the plug 0, and forms a continuation of the valve-controlled oil-passage c therein. The other end of the small tube 1) extends up a short distance only into the glass tube G, and this end forms a nozzle, 1), from which oil is discharged. The annular space between the two pipes E and b is designed to be filled with water, which water extends up into the glass tube some distance above the nozzle 1). Consequently oil which passes over into and descends through the oil-outlet pipe will emerge from the nozzle b and pass up in visible drops through the body of. water contained in the glass tube. The water between the two pipes E and 1) serves as a water-shield to keep the lubricant cool and effective, and in practice is productive of excellent results.

Having thus described my improvements, whatI claim, and desire to secure by Letters Patent, is-- The oil-chamber, the oil-outlet pipe, and the pipe I, in combination with the concentric water and oil pipes E b and the glass tube Gr, substantially as and for the purposes hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 30th day of December, 1880.

JOHN ABSTEBDAM.
